Debugging the heating system

The whole summer I had the suspicion that the underfloor heating in one room of our flat is still on. We had dialed all thermostats down to “off”. But still the floor was somewhat warmer than in the other rooms. I blamed this on the sun shining in in the afternoon. But now that it’s colder outside and one can definitely tell if the heating is on I was sure something is broken. I opened the control unit compartment where all the pipes arrive and the valves are located. There were fortunately flow indicators on each pipe. So I could clearly see that the room in question had a constant flow of 1L/min while all other rooms were completely off. I turned the thermostat all the way up and could confirm the flow rate increase as well. But it never went down below 1L/min. Also disassembled the thermostat to check if that can be broken in this way. But it’s a simple bi-metal switch.

I’ve turned off the whole heating system now to stop the unnecessary heating and tried to make an appointment with a craftsman for repair. Earliest slots are at the end of October 😳

OS Updates

Apple released new iOS 18 and new macOS 15 (Sequoia). So it was time to update. All supported devices updates without an issue. Everything working so far. Kind of a non-event.

Exercise

I was really lazy over the summer. Partially due to the gym in the office being closed for renovation… But this week I did a longer walk (to and from the office) and a first run in the park to get into it again..
